Application led October 18, 1926, Serial No. 142,488, and in Italy :fune 16, 1926.

This yinvention regards improvement-s in parachutes and particularly the attachment of the user to the vertex of the rope system and the devices for breaking or cutting, at

the moment of the leap, the cord of the bag containing the parachute.

The invention is illustrated by way of example in the annexed drawings in which Fig. 1 is a front view of the waist-belt of the aircraft pilot, with its various att-aching or hooking devices, i,

Fig. 2 a partially sectioned elevation of these devices shown in their hooked position in full lines, and in' their unhooked position in dott-ed lines,

Fig. 3 represents the devices for breaking or cutting the cord of the knapsack containing the parachute, and

Fig. 4 is alongitudinal section of the said breaking or cutting devices..

In the said figures A and A are the two parts of the waist-belt, solidly connected to the knapsack. At 1 on part A two sprocket chains are fixed, passing in the interior of two boxes 2 connected together by The covers 4 of said boxes 2 are hinged at 5 on the hindmost sides of the box-es. To the front part of covers 4, at 6, the buckle 7 is hinged. i

The said covers in their interior have teeth 8 'corresponding to the links of the sprocket chains. When the covers 4 are raised their teeth 8 are disengaged from the sprocket chains'and the boxes 2 are free to slide on,

the chains so that the clasping of the buckle 7 may be regulated according to the circumference of the waist of the bearer. On part A of the waist-belt the clasping and unfixed. They consist of a part 9 rigidly fixed to the waist-belt, the raised sides 10 of which form thc hooks of buckle 7,V whilst the sides 11 form the sockets for the passage of the lockbolts 12 slidable in a bearing or sheath at 13 to the fore end'of the moveable part 14 hinged in turn, at 15, on the said rigid part 9. On the .part 14 two levers 16 are pivoted which operate the lock-bolts 12 so as to disengage lthem from the sockets 11 in the act of unclasping. lThe levers 16 pass through holes vprovided in the bolts 12 so that when they are pressed toward one another in the direction of the arrows in Fig.' 1 the bolts are withdrawn from; the sockets 11. 17 is a reaction abow 3.

- buc spring controlling the movements of the lockbolts.

18 are elastic members which in position of closure keep the buckle 7 in place, and also covers 4 of boxes 2 are members 19.

At the top of part A of the waist-belt a ring of the piston is connected to a cord or Bowden line.

kept closed by said Two of the said devices are applied4 to i line 23, the one acting automatically at the moment of the leap, the cord 30 being attached to the waist belt, whilst the other, of the Bowden system, is operated by lever 31 at the will of thepilot.

Clasping and unclasping of waist-belt is effected as follows:

After the pilot has donned the knapsack which is kept in place by brace 21 attached to ring 2O lof part A of waist-belt, the buckle 7 is fastened according to circumference of 2 to slide on the sproc 4 being raised. To the end of the said covers, at 6, the buckle 7 is hinged. On closing the covers 4 their rigid teeth 8 engage the links of the sprocket chains thereby effecting closure, whereupon buckle 7 is turned down so as to bend the elastic members 18 and placing itself under the latter so as to engage hooks 10 of fixed .part 9 and effect a sure and solid con` nection of parts A and A of waist-belt. The pilot then attaches 4himself to his seat by means of ring 22.

In order to promptly disengage himself the direction of the arrows, the two levers 16 pivoted to the moveable part 14, which cause the lockbolts 12 to re-enter in 13 from their sockets 11 on the fixed part 9. By this first operation the moveable part 14 turning on its hin es 15 is raised thereby releasing the ile 7 from'the hooks 10. The buckle being moveable and rotatably connected at 6 to waist of bearer, causing the bow 3 zpd boxes et chains, t e covers nected at one end to covers 4 raises the latter thereby disengaging' the teeth 8 from the sprocket chains, Wlth the result of the tWo being disengaged, Figs. 1 and 2. In the said figures the outermost free ends of the sprocket chains are omitted for the sake of clearness.

It is understood that all of the parts and subject matter of the present improvementsmay be modified accordingvto circumstances Without departing from the spirit of the invention.

Having now particularly described and ascertained the nature of said invention and in what manner the same is to be performed I declare that What l claim is In a parachute, a Waist belt, chains conthe belt, boxes slidable relative to the chains, means connecting said parts A A of the Waist-belt boxes, said boxes including each a hinged cover having teeth adapted for insertion in the chain, a movable buckle connected to the free end of each cover, a plate connected with the other end of the Waist belt, hooks associated with the last mentioned plate and engaging the buckles, the last mentioned plate being provided with lugs and being hinged to a movable plate provided With a sheath, lock bolts in said sheath, spring means coacting with said lock bolts, said lock bolts engaging pipes provided on the last mentioned plate, and hinged lever arms running through holes provided in the lock bolts and operating in conjunction with the latter.

lin testimony whereof l have hereunto signed my name. Y GTUSEPPE FURMANIK.
